Abstract: 1,251,544. Spring drum stress-limiting devices. H. KUHL. 14 May, 1969 [14 May, 1968], No. 24523/69. Heading B8B. [Also in Division F2] A device for preventing the transmission of sudden loads and temporary accelerations between a towing and a towed body, comprises a drum 9 on which is wound a cable 3 for towing, the drum being restrained from rotating suddenly in one direction by a multi-disc brake 11, 12 and being rotatable by a spring in the other direction without any braking action. The brake comprising discs 11, 12 splined to a hub 20 and the drum 9 has its biasing force adjustable by a nut 22 acting to compress the discs through a cup spring 23. A clutch member 25 on which the hub 20 is splined is formed with ratchet teeth 27 engageable under the force of a spring 26, with teeth on a disc 28 rigid with the drum housing 14, 15. The teeth are formed to lock the hub during cable pay-out once the braking force has been overcome, and to permit free-wheeling of the hub in the pay-in direction by means of a spiral spring 10 once slack develops in the cable. The drum may be manually rotated by a handle 34 once the clutch teeth 27 are disengaged. During towing, one end of the cable 3 is secured to one body and the device housing is secured to the other body.

Abstract: 1,252,110. Controlling burners. SIEMENS A.G. 4 Oct., 1968 [4 Oct., 1967], No. 30244/71. Divided out of 1,249,999. Heading F4T. A flame monitoring device includes two flame sensors disposed in or adjacent the flame so that extinction thereof results in unequal changes in a common characteristic respectively exhibited by the two sensors in a dissimilar manner as regards temperature dependence, thereby causing emission of two different output signals from which is obtained a differential control signal indicative of the extinction. This control signal is fed to fuel supply control means, e.g. an electromagnetic valve, to reduce or cut off the supply of fuel, which may be liquid or gaseous fuel, or pulverized coal. The common sensor characteristic may be change in magnetic flux, or electrical resistance, or dimension, with temperature. A liquid or gaseous coolant, e.g. the flame combustion air, prevents the temperature of the sensors from exceeding a predetermined maximum value.

Abstract: 1314326 Measuring conductivity of milk NATIONAL RESEARCH DEVELOPMENT CORP 29 June 1970 [30 June 1969] 33032/69 Heading G1N [Also in Division H1] Bovine mastitis is detected by passing the milk from each teat into respective ones of four cells 15-18 where its electrical conductivity is sensed by coils or electrodes in respective arms of a bridge circuit, the bridge becoming unbalanced if the milk from one teat has an abnormal conductivity due to mastitis. In Fig. 1, the four cells are arranged within a hemispherical member 10 having a central boss 25 and four radial barriers 21-24. Member 10 is attached by a bayonet catch 31 to the base which has a common outlet 19 under the boss 25. The inlet tubes 11-14 are arranged to cause the milk to swirl in the cells so that any foam rises away from the coils 26-29. Inductance coils (26-29) have their outer turns connected to the oscillator to reduce capacitive coupling and are all energized in the same sense to reduce inductive coupling. For cleaning, the apparatus is held upside down Fig.4, (not shown) and a detergent germicide is passed in through pipe 19 and impinges on the concave end of boss 25 to be scattered all over the cell surfaces. In Fig. 5 each of the four cells has two electrodes 66, 67; 68, 69; 70, 71; 72, 73 which with insulation 74, 75, 76, 77 forms a substantially planar surface. The electrodes are connected in a bridge circuit in which fixed resistors can be switched in series with the cells Fig. 6, (not shown) or a common resistor (111), Fig. 7, (not shown) adjustable to represent uninfected milk, can be substituted for each cell in turn. A lamp may be used to detect bridge unbalance, the lamp becoming extinguished when the resistor (111) replaces the cell containing the infected milk. Five magnetically operated reed switches (105-109) may be arranged to operate in correct sequence as an indexing arrangement (113, 118), Figs. 8 and 9, (not shown carrying magnets (115, 116) is manually rotated against the action of a restoring spring (119) which returns the arrangement to its initial setting.
